Commission officials said the type of dry cask selected by Entergy was already in use at eight American nuclear power plants.

Its site is now proposed for a "dry cask" waste storage system that would hold spent nuclear fuel.

But it appears willing to store the rods in dry casks to keep them from corroding.

Meanwhile, the waste is being moved into "dry casks," concrete and steel silos designed to last for decades.

Permission has been granted to store 420 dry casks on the site.

A centralized storage facility using dry casks is located at Ahaus.

The other way to store fuel is to put it in dry casks, massive concrete and steel boxes filled with inert gas.

Some utilities have moved spent fuel into dry casks, a process they say is expensive and forces their customers to pay twice for fuel storage.

The spent fuel is stored onsite in 34 dry casks.

So, right now, nuclear power plants store their cooled spent fuel in containers called dry casks.
